The tools required for the gas conversion are:
- Flat and Phillips Screwdrivers
- #40 torx driver
- Digital CO2 Gas Combustion Analyzer
- This procedure must be performed by a licensed gas technician
All of the Bosch Therm condensing heaters such as the C1210ESC/C1210ES/C1050ES/C950ES/C800ES and Integra 500 CANNOT be converted as the units have a special plate built into the burner tray. This extra plate in the burner tray was designed and instlled to give the heater the ability to be installed at higher elevations up to 8000'.
Also the Bosch Therm 660EF/660EFO/520PN/520HN/425HN/425EF/330PN CANNOT be converted as they are not designed at all for gas conversion.
